A Monograph of Culicidae. 
the mesonotum thin, like the median ones, but paler; in front of 
the scutellum they are again broader and pale, whilst a dense 
mass of golden-yellow bristles extends over the roots of the wings ; 
the thick- and thin-scaled lateral areas are marked off by a semi- 
bare, dark, curved line in some specimens but not in others ; 
scutellum black, with broadish, curved, pale golden scales and 
numerous pale golden border-bristles; metanotum deep purplish- 
brown ; pleurae dark purplish-brown, with patches of flat pale 
scales, sometimes densely white scaled. When denuded there 
are traces of two dark longitudinal lines on the mesonotum. 
Abdomen deep black, with narrow white basal bands which 
widen out laterally, forming large lateral patches; sometimes 
these bands are distinct, at others they do not show, only the 
large lateral extensions being seen ; on the last segment there 
are also a few pale apical scales ; border-bristles fine and pale ; 
lamellae long, black and hairy; venter whitish scaled, with three 
more or less distinct dark lateral patches. In some specimens 
the abdomen has yellowish basal bands, and in others these 
bands spread out in the middle of the segments, or the flaxen 
scales may be scattered indiscriminately about. 
Legs dark brown; the Coxae brown, with creamy-white scales ; 
femora pale yellowish-white at the base and beneath, dark brown 
above towards the apex, which is white ; tibiae dark brown, 
paler beneath ; hind tibiae slightly longer than the metatarsi ; 
tarsi dark brown, almost black; femora, tibiae and metatarsi 
bristly ; ungues all equal, uniserrated and thick. 
Wings large, with densely scaled veins; longer than the 
abdomen, covered along the veins with deep brown scales, the 
lateral ones long and thin ; fringe brown, except at the base, 
where it has a pallid, almost whitish hue; fork-cells rather 
short; first sub-marginal cell longer and narrower than the 
second posterior cell, its stem more than half the length of the 
cell; stem of the second posterior cell a little longer than the 
cell; posterior cross-vein about the same length as the mid cross¬ 
vein, and about its own length distant from it; border-scales 
darker than the fringe. The fifth and sixth long veins are 
particularly densely scaled. Halteres densely clothed with pale 
yellowish-white to white scales. 
Length. —7 to 9 mm.
